As spring starts earlier, the date of the last hard frost is not changing," Inouye said, so there is a longer period between the time the first blossoms appear on fruit trees and wildflower plants and the frost-free date, increasing the chance that buds and flowers could be killed by frost.
In the past, the tree-bark eating beetles were killed off during cold winters, said Inouye, who does field research in Colorado. Without temperatures of minus 30 degrees F (minus 34.4 degrees C) or lower, bark beetles thrive, producing two insect generations a year instead of just one, Inouye said. That means there could be up to 60 times as many insects attacking trees in any given year, researchers at the University of Colorado Boulder found.
The deadly disease called Parvo hasn't died off this winter. "With our current mild warm temperatures it's actually flourishing in this environment," Breyer said.
Maple syrup producers say they are already weeks ahead of schedule, and if it doesn't get cold again soon there will be a very short season. Maple trees are among the first trees to bloom, and once that happens the syrup harvested is of a much lower quality
Unseasonable warmth can put plants and migrating pollinators out of sync, Inouye has found. In Colorado, he said, broad-tailed hummingbirds normally spend winters in Mexico and return to the United States for the summer, in time to feed on nectar in certain plants. Recently, though, the plants are flowering before some of the birds arrive, meaning less nectar for the hummers and less pollination for the wildflowers, which then produce fewer seeds.
"When plants get in this off-kilter blooming, sometimes it doesn't coincide with the life cycle of the pollinator," said Holly H. Shimizu, the executive director of the United States Botanic Garden in Washington told the New York Times. "If pollination doesn't occur, then we don't get the fruit production."
Beekeepers are used to the typical threats like parasites, fungal infections and environmental concerns such as habitat loss and air pollution. But this year, the unseasonably warm winter may pose the biggest threat to New Jersey's honeybees. Usually semi-dormant in the winter, bees have been active and eating through their reserve honey stores, which are suppose to last until spring. Beekeeper Joseph Lelinho of Hilltop Honey in North Caldwell is predicting a rise in the cost of honey from the loss of area hives.
According to Curtis, warm winters such as this year’s can also cause population bursts in non-hibernating animal populations, because these animals experience less winter related fatalities in winters with warm weather. The growing deer population is an example of such a population boom. Population booms cause animals like deer to deplete their food supply earlier in the year than they normally would. This forces many of the animals to search for different food options, which has a ripple effect on the ecosystem.
Still another climate-related factor will cause mosquito swarms to inflate: a serious dip in bats. Mosquito-munching bats have been dying off, due to a fungus that has decimated the population. “We may have lost five and a half to six and a half million bats in eastern North America in the last five years,” Curtis said. The fungus may be causing them to wake early, itching and hungry. And when they emerge unexpectedly in January or February looking to feed, they starve to death Read more: www.foxnews.com...
Less reliable winter snow cover may hurt over-wintering of some perennial crops and flowers. Hotter summers may cause heat stress even in warm-season crops such as tomatoes
Many crops show positive responses to elevated carbon dioxide and lower levels of warming, but higher levels of warming often negatively affect growth and yields. Extreme events such as heavy downpours and droughts are likely to reduce crop yields because excesses or deﬁcits of water have negative impacts on plant growth. Forage quality in pastures and rangelands generally declines with increasing carbon dioxide concentration because of the effects on plant nitrogen and protein content, reducing the land’s ability to supply adequate livestock feed. Increased heat, disease, and weather extremes are likely to reduce livestock productivity.

Other then temperature, what are your observations of your area?

I don't know how many of you live in Vancouver, but I swear it's been relatively normal all year.
it rained. typical.
not to discredit your thread at all, but speaking for my region, it's been average and everything has happened as we know it should.
